Frequently Asked Questions
What is a washable pre-filter?
A washable pre-filter is designed to effectively capture large amounts of dust and particles before they reach the main filter. It can be easily cleaned and reused, reducing waste and operating costs.
What is the filtration efficiency of these pre-filters?
These pre-filters offer a high filtration efficiency of 95% for particles that are ≥5μm in size, ensuring excellent air quality improvement.
What filtration class do these filters belong to?
All models of our washable pre-filters conform to the G4 filtration class standard.
Can I order custom sizes for my specific installation?
Yes, while we offer standard dimensions (such as 595*595, 495*495, and 295*595 in various thicknesses), special sizes are available upon request to fit your specific HVAC or dust collection system.
How does the low pressure drop benefit my system?
A low pressure drop maintains optimal airflow with minimal resistance. This ensures that your air conditioning and dust collection systems operate with high energy efficiency, saving on electricity costs.
What is the maximum initial and final pressure drop?
The initial pressure drop (I.N.P) is generally ≤40/80 pa depending on the airflow, and the final pressure drop (F.N.P) before cleaning or replacement is required is ≤255 pa.
